Definition / general
  • Uncommon complication of adult HSV1 or HSV2 infection
  • Usually pregnant women (mean 31 weeks) or immunocompromised patients
  • Often clinically unsuspected (Liver Transpl 2007;13:1428)
  • Rapid downhill course with acute liver failure, usually fatal (up to 81% of adults) due to massive hepatic necrosis (Clin Transplant 2009;23:37), even with rapid antiviral therapy or liver transplanation (Liver Transpl 2008;14:1498)
  • Often not diagnosed until autopsy due to nonspecific clinical features
  • Better survival in children than adults (J Hepatol 2011;55:1222)
Laboratory
  • Sudden, marked elevation of ALT or AST, fever, leukopenia
Case reports
Microscopic (histologic) description
  • May have random areas of bland coagulative necrosis with minimal inflammatory response
  • Hepatocytes may have multinucleated forms
  • At edge of necrotic areas, cells contain intranuclear inclusion surrounded by clear halo with peripheral chromatin margination (eosinophilic Cowdry type A inclusion and basophilic Cowdry type B), with ground glass nuclei
  • Intranuclear inclusions highlighted with Feulgen stain
  • Specific immunostain is available
